TANK PUMP.

Application filed September tractors, or the like.

, An object of theinvention is to make provision whereby explosive or,highly inflammable hydro-carbons can be safely transferred fromonecontainer tov another, thus yto enablea userto store a ,quantity ofgasoline and to drawvthe gasoline from such storage Las may berequired,and with perfect safety. f

Y Viiniobject of this inventionl to make provisionv whereby air pressurecan be cheaply, simply, easily and safely employed to transfer-*gasolineliquid fuelsand other liquids .fromone container to another.

y y Incarryingy out this invention, I provide for an air pumpbarrelfafitting which .is y

adapted atfone end, Vfor an airtight connection tosaid barrel, and attheother,l end for attachmentl to a container, ,andl provided with a wayadapted to' connect at one end with a pipe in said container, and at theother end with a pipe outsideof said container, said fitting also beingprovided with a valved passage adapted to communicate between said pumpbarrel and said container, and with a vent connected to said passage.

The invention includes the various parts and combinations of parts whichI have produced in carrying out this invention.

The principle of the invention is that means are provided whereby airpressure may be introduced onto the top of a body of liquid in acontainer and when so applied will force the liquid out from a pipearranged for that purpose, and further means are provided whereby theair pressure introduced into the container may be readily relieved whenthe desired transfer of liquid from one container to another has' beeneffected.

Other objects, advantages and features of invention may appear from theaccompanying drawing, the subjoined detailed description and theappended claims.

The accompanying drawing illustrates the invention. v

Figure 1 is a fragmental, axial section of a tank constructed inaccordance with this invention, and arranged to transfer gasoline from agasoline drum to a users tank.

Fig. 2 is an elevation of the device shown 5, 1923. *seriaino. 661,015.

of the device shown opposite the lcap a threadedyportion 5 adapted to besecured air tight toa seat 6 at one end ofv ay fitting 7, `whichjisshownprovided with an internally threaded seaty adapted to screwV on thethreaded ortion 5. vThe fitting 7 is provided with' a ent pas- Vsage 8vwhichis adaptedY at its ends asbyr the threaded portions 9 andvlO toconnect with rpipes 11 and 12 adapted to deliver liquidl to,

and'to discharge itfrom thebent passageS. The `ittingisprovided with apin 13 having a threaded portion 14 vadapted to screw into the` bung'15of a transportation or storage y drumor'ta'nk 16.

Said'iitting is provided with a valve way 17` extending from the barrelseat 15 throughr the threaded pin 13 and said way is provided with avalve seat 18 in which is seated a valve 19 held in place by a valvespring 20, that in turn is held in place by an air vent petcock 21. p

The way 17 comprises a verticalbore a, a lateral bore b terminating inthe valve seat 18, and a vertical bore c terminating at the end of thethreaded pin 13 and the lateral bore and its valve seat are coaxialwith-the horizontal spring chamber l which is of greater diameter thanthe ball valve 19 and the spring 20, and is threaded to receive thpetcock.

In practice, the fitting with pump cylinder 1 and the receiving pipe 11attached, will be applied to the drum or tank from which the delivery isto be made; this-is done by inserting the pipe 11 into the bunghole ofthe drum or tank and screwingthe pin 13 into the bunghole; the pipe 11connected to the fitting extends below the liquid level e; the petcockbeing closed, plunger 22 of the pump will be operated to compress airinto the drum through the way 17, causing air pressure on top of theliquid and causing the liquid to iiow up the pipe 11 and out throughpassage' l. An appliance of the character described,

comprising a pump; a liquid container; a

fitting connecting the pump and theliquidl container, and formedwith alooreI for admitting air under pressure from the pump to the interiono'fthe containeriabove the level of the liquid therein, and also formedwith a liquidoutlet passage; an outletpipe threaded into one end of saidpassage and extending into the container to deliver liquid underpressure therefrom,y said fitting vfurther provided with a horizontallyextending lateral passage communicating With said here; a valve seatformed at the intersection of the lateral passage and bore; a ball valvefor said seat; al spring disposed in said passage for normallyholdingsaid valve upon said seat, andv a stop "cock in said lateral passageadapted for actuation to relieve the pressure in said container throughsaid bore and passage.

threaded pin on said fitting adaptedY to screwVV into the bung ofthestorage tank, said iitting having a passage extending therethrough, apipe Ythreaded into said passage and eXtending into the liquid in saidtank,'to deliver the liquid therefronnsaid itting having an irregularbore extending from the pump cylinder to the interior of the tank andrahorizontally extending` lateral passage@openingr into said loore, a ballvalve in said passage, and a seat 'for saidvalve fliormed attheintersection of the passage with saidv bore, a spring in said passageadapted for actuating the valveto Iclosedposition, and a'stop cock insaid lateral passage controllingthecommunication betweenthe storage tankand the atmosphere.
